Answer
$g=4$
Work Step by Step
Use the Division Property of Equality by dividing both sides of the equation by $5$:
$$\begin{align*}
\frac{5g}{5}&=\frac{20}{5}\\
g&=4\end{align*}$$
Check the solution by substituting $4$ to the variable in the given equation:
$$\begin{align*}
5g&=20\\
5(4)&\stackrel{?}{=}20\\
20&\stackrel{\checkmark}{=}20\end{align*}$$
Thus, the solution is $g=4$.
